Log and Capture GH1 footage using HV20 as deck.

A client gave me some archive tapes (dv) to use for a doc. I believe they were shot on a Canon Gl2 or another older DV camcorder. The problem is I only have my HV20, which requires that FCP be set to HDV. I can get the camera recognized, but it gives me an error which reads:

"Capture was aborted due to lack of incoming data from device. Check your connections and that the deck is playing."
